<p>The present invention relates to a method and system for communicating via transmission signals in a multiple-user communication system comprising multiple user devices and an access point device. The transmission signals, also referred to as rate division multiple access (RDMA) signals, enable implementations of efficient multiple-user communication, identification, sensor or localization systems and networks. A multiple-user communication system for communicating via transmission signals um(t) comprises an access point device for receiving the transmission signals um(t) from multiple user devices, thereby each of the transmission signals has a defined pulse rate 1/Tm, with Tm being the pulse period and m = 1, 2, 3, ... M. The system further comprises a first user device using a first pulse rate 1/T1 for communicating to the access point device and each additional user device using yet a further pulse rate 1/Ti that is different to each other pulse rate 1/Tm in use, with i = 1, 2, 3, ... M, where m <> i, to communicate to the access point device. The access point device differentiates the multiple user devices based on the pulse rate 1/Ti of received transmission signals si(t).</p> |
